Table 1 Lithium disilicate and zirconia: pros and cons

From: Current status on lithium disilicate and zirconia: a narrative review

Lithium disilicate
Pros Cons
• excellent optical characteristics and good mechanical properties • clinical versatility • biocompatibility • favourable abrasiveness • marginal accuracy and internal fit • high strength of adhesion to the substrate • monolithic and layered • glaze coating and fluorapatite ceramic veneering can increase wear • critical to adjust intraorally • chipping of the veneering ceramics
Zirconia
Pros Cons
• excellent mechanical characteristics and good optical properties • excellent biocompatibility and low plaque retention • favourable wear behaviour • implant abutments for esthetic sites • crack-hindering potential (through PTT) • marginal accuracy and internal fit • monolithic and layered • opacity • unetchable with conventional methods • low temperature degradation and aging • critical to adjust intraorally • glaze coating and fluorapatite ceramic veneering can increase wear • chipping of the veneering ceramics
